Characterizations on sodium chloride Admixtured l-Asparagine monohydrate by slow evaporation technique

The title compound LAM prepared by using AR-grade L-asparagine and NaCl. It is dissolved in de-ionized water to get NaOH and HCl and these two are used as solvents. Solubility of LAM can be determined by gravimetric method. Using slow evaporation technique (SET), the grown crystal can be obtained in 20 days. The crystallanity of the crystal can be confirmed by X-ray diffraction. The crystals, by X-ray (EDAX) confirm the composition of elements in the crystal. The structure can be determined from Single X-ray diffraction. It shows that it belongs to orthorhombic system with space group P212121. The various functional group associated with the crystal can be obtained from FTIR study. The NLO property can be confirmed by SHG test. It shows that, the grown crystal is 0.38 times that of KDP. The optional property of the grown crystal can obtained from UV-Visible transmittance study. The hardness of the grown crystal can be obtained from Vickers micro hardness test. The dielectric property and ac conductivity can be obtained from dielectric studies. From this activation energy can be obtained. An elementary analysis is carried out for the grown crystal by employing energy dispersive analysis.
